Description
본 발명은, 오폐수처리장치에 관한 것으로서, 보다 상세하게는, 오폐수중의 유기성분을 미생물을 이용하여 분해처리하는 오폐수처리장치에 관한 것이다.The present invention relates to a wastewater treatment apparatus, and more particularly, to a wastewater treatment apparatus for decomposing organic components in wastewater using microorganisms.
산업화 및 도시화의 발전이 가속화되어 삶의 질이 풍요로워짐에 따라, 상대적으로 대규모의 생활하수 및 산업폐수가 발생되어 환경오염 문제의 심각성이 더해가고 있으며, 수질의 오염에 의해 국민의 식수원인 상수원조차도 상당히 위협을 받고 있는 실정이다. 이러한 생활하수 및 산업폐수를 정화시키기 위해 대규모의 하수종말처리시설 또는 폐수처리장치들을 대부분 도시단위 또는 공장단위에 설치하여 가동하고 있으나, 설비규모가 매우 크고, 설치 및 유지보수에 대한 막대한 비용이 소요된다.As the development of industrialization and urbanization accelerates, and the quality of life is enriched, a relatively large amount of living sewage and industrial wastewater are generated, increasing the severity of environmental pollution problems, and even water sources, which are people's drinking water sources, are polluted by water pollution. The situation is quite threatened. Although large-scale sewage treatment facilities or wastewater treatment devices are installed and operated in urban or factory units to purify such domestic sewage and industrial wastewater, the facilities are very large and require huge costs for installation and maintenance. do.
따라서, 비교적 규모가 작은 사업장 및 업소 등에서는 오폐수를 자체처리하기 위해 정화처리시설을 구비하는데 있어서, 통상 설비의 규모가 대형이며 복잡한 기계장치로 구성되어 있고, 설치 및 유지보수에 막대한 비용이 소요되어 상당한 부담감을 갖게 되어, 정화처리시설을 구비하는 것이 곤란하여 정화처리되지 않은 오폐수를 그대로 방류시킬 뿐만 아니라 정화처리시설을 구비한 후에도 과다한 운영비와 운영 미숙으로 인하여 정상가동을 하지 않고 정화처리되지 않은 오폐수를 그대로 방류시킴으로써, 하천의 수질을 크게 악화시키고 있다.Therefore, a relatively small workplace and a business has a purification treatment facility for treating wastewater by itself, and is usually composed of a large and complex mechanical device, and requires huge costs for installation and maintenance. There is a considerable burden, and it is difficult to have a purification treatment facility, which not only discharges unpurified wastewater as it is, but also does not operate without normal operation due to excessive operating costs and inadequate operation even after a purification treatment facility is provided. By discharging the water as it is, the water quality of the river is greatly deteriorated.
이러한 문제점을 고려하여 큰 설비를 설치함이 없이 경제적으로 오폐수를 정화처리하는 방법으로서 살수여상법이 알려져 있다. 살수여상법은 여상에 살수된 오폐수가 쇄석, 율석, 무연탄괴 등의 여재사이를 통과하는 동안에 여재의 표면에 부착 성장하고 있는 미생물막의 생물화학적 작용에 의하여 오폐수중의 유기성분을 제거하는 처리법으로서, 오폐수의 처리효율이 낮고 악취 및 해충의 발생으로 인하여 이용을 기피하고 있으나, 최근에는 오폐수의 처리효율을 향상시키고 악취 및 해충의 발생을 방지하기 위해 여재를 톱밥이나 목편을 이용한 살수여상법이 각광을 받고 있다.In consideration of these problems, the sprinkling filter method is known as a method of purifying wastewater economically without installing a large facility. The sprinkling water treatment method is a treatment method that removes organic components in waste water by biochemical action of microbial membrane that grows and adheres to the surface of the filter media while the wastewater sprayed on the filter passes between the media such as crushed stone, yulseok and anthracite coal. In order to improve the treatment efficiency of wastewater and to prevent the occurrence of odors and pests, the sprinkling method using sawdust or wood chips has been widely used. I am getting it.
그런데, 이러한 톱밥이나 목편을 여재로 이용한 종래의 오폐수처리장치에 있어서는, 고농도의 유기성분과 고형물을 가지고 유입되는 오폐수로부터 침전분리조에서 고형물만을 침전분리시킨 후, 침전분리조에서 배출된 오폐수를 바로 살수여상조로 유입하므로, 사용시간이 경과함에 따라 목편층의 오폐수공급영역에는 슬러지가 축적되어, 즉 살수여상조의 부하가 증대되어 목편층내로 처리될 오폐수의 유입속도가 저하될 뿐만 아니라 살수여상조내에 막힘현상이 발생하여 오폐수의 처리효율이 저하되는 문제점이 있다. 또한, 유입되는 오폐수의 유기성분의 농도가 높을 경우, 살수여상조의 부하가 증대되어 오폐수의 처리가 곤란한 문제점이 있다. 그리고, 오폐수처리를 할 때 발생되는 슬러지를 저장하는 별도의 슬러지 저장조가 필요하게 되어, 오폐수처리장치의 설치면적이 커지는 문제점이 있다.However, in the conventional wastewater treatment apparatus using such sawdust or wood chips as a medium, after sedimentation and separating only the solids from the sedimentation tank from the wastewater introduced with a high concentration of organic components and solids, the wastewater discharged from the sedimentation tank immediately sprinkled As it flows into the filter tank, sludge accumulates in the wastewater supply area of the woody layer as the use time elapses, that is, the load of the watering filter tank increases, which not only decreases the inflow rate of the wastewater to be treated into the woody layer but also clogs in the watering tank. This occurs and there is a problem that the treatment efficiency of waste water is reduced. In addition, when the concentration of the organic component of the waste water flowing in is high, there is a problem in that it is difficult to treat the waste water due to an increase in the load of the spraying tank. Then, a separate sludge storage tank for storing the sludge generated when the waste water treatment is required, there is a problem that the installation area of the waste water treatment apparatus increases.
따라서, 본 발명의 목적은, 살수여상조로 공급되는 오폐수의 유기성분을 줄일 수 있는 오폐수처리장치를 제공하는 것이다.Accordingly, it is an object of the present invention to provide a wastewater treatment apparatus which can reduce the organic components of wastewater supplied to the spraying tank.
본 발명의 또 다른 목적은, 침전분리조로 유입된 오폐수의 농도가 높더라도, 오폐수처리를 원활히 할 수 있는 오폐수처리장치를 제공하는 것이다.Still another object of the present invention is to provide a wastewater treatment apparatus capable of smoothly treating wastewater, even if the concentration of wastewater introduced into the sedimentation separation tank is high.
그리고, 본 발명의 또 다른 목적으로서, 별도의 슬러지 저장조가 필요하지 않은 오폐수처리장치를 제공하는 것이다.Another object of the present invention is to provide a wastewater treatment apparatus that does not require a separate sludge storage tank.
도 1은 본 발명에 따른 오폐수처리장치의 흐름을 개략적으로 도시한 공정도이다.1 is a process diagram schematically showing the flow of wastewater treatment apparatus according to the present invention.

The purified water is diluted and precipitated, and when the amount of influent is small, the purified water is returned to smoothly treat the waste water.
이상과 같이, 침전분리한 오폐수를 바로 살수여상조로 공급하지 않고 접촉폭기하여 오폐수중의 유기성분을 분해처리한 후, 접촉폭기조에서 미생물의 분해에 의해 생성된 슬러지를 침전조에서 침전시켜 침전분리조로 반송함으로써, 살수여상조에 유입되는 오폐수에 슬러지가 유입되지 않아 살수여상조의 살수부의 막힘현상을 방지하고, 또한 살수여상조의 부하를 경감하여 오폐수를 원활하게 처리할 수 있으며, 별도의 슬러지 저장조가 필요하지 않게 된다.As described above, the sewage waste water separated by sedimentation is not directly supplied to the spraying water tank to decompose organic components in the waste water, and the sludge produced by the decomposition of microorganisms in the contact aeration tank is precipitated in the sedimentation tank and returned to the sedimentation tank. By doing so, sludge does not flow into the wastewater flowing into the spray tank, preventing clogging of the spray tank and reducing the load of the spray tank, so that the waste water can be smoothly treated and a separate sludge storage tank is not required. do.
또한, 유기성분의 농도가 높은 오폐수가 유입되더라도, 여과조로부터 침전분리조로 정수를 반송하여 유입된 오폐수의 농도를 희석함으로써 오폐수처리장치의 부하를 경감시켜 오폐수를 원활하게 처리할 수 있다.In addition, even if wastewater having a high concentration of organic components is introduced, the purified water is returned from the filtration tank to the sedimentation separation tank to dilute the concentration of the introduced wastewater, thereby reducing the load on the wastewater treatment apparatus and smoothly treating the wastewater.
이상 설명한 바와 같이, 본 발명에 따르면, 오폐수를 원활하게 처리할 수 있고, 별도의 슬러지 저장조가 필요하지 않은 오폐수처리장치가 제공된다.As described above, according to the present invention, there is provided a wastewater treatment apparatus which can smoothly process wastewater and does not require a separate sludge storage tank.
